Updated gawk packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The gawk packages provide the GNU version of the text processing utility awk. Awk interprets a special-purpose programming language to do quick and easy text pattern matching and reformatting jobs.

Bug Fix

BZ#829558
Prior to this update, the "re_string_skip_chars" function incorrectly used the character count instead of the raw length to estimate the string length. As a consequence, any text in multi-byte encoding that did not use the UTF-8 format failed to be processed correctly. This update modifies the underlying code so that the correct string length is used. multi-byte encoding is processed correctly.
All users of gawk requiring multi-byte encodings that do not use UTF-8 are advised to upgrade to these updated packages, which fix this bug.
An updated gawk package that fixes three bugs is now available for Red Hat Enterprise Linux 6.
The gawk package contains the GNU version of awk, a text processing utility. AWK interprets a special-purpose programming language to do quick and easy text pattern matching and reformatting jobs.

Bug Fixes

BZ#648906
Prior to this update, the gawk utility could, under certain circumstances, interpret some run-time variables as internal zero-length variable prototypes. When gawk tried to free such run-time variables, it actually freed the internal prototypes, that were allocated just once due to memory savings. As a consequence, gawk sometimes failed and the error message "awk: double free or corruption" was displayed. With this update the problem has been corrected and the error no longer occurs.
BZ#740673
Prior to this update, the gawk utility did not copy variables from the command line arguments. As a consequence, the variables were not accessible as intended. This update modifies the underlying code so that gawk makes copies of those variables.
BZ#743242
Prior to this update, the Yacc interpreter encountered problems handling larger stacks. As a consequence, the Yacc interpreter could fail with a stack overflow error when interpreting the AWK code. This update enlarges the stack and Yacc can now handle these AWK programs.
All users of gawk are advised to upgrade to this updated package, which fixes these bugs.
